That is incredibly interesting. Thank you. Since my adopted son's father has an ASD, me and my partner are concerned about a few major patterns of development as we've watch our son grow up. I think, as a precaution, we will be going through the motions of exploring this over next month or two.

I'm especially grateful for any useful insights into what may be. Not to overthink it but to prepare for the outcome.

Your comment gives me another opportunity for my own study to help my son if the outcome is so. Again, thank you.

As an edit, we are not simply assuming this is the case but actually in collaboration with health professionals, who have referred us successively towards this point. I didn't make it clear that I'm not actually doing a 'DIY diagnosis', which is wrong when it comes to issues like this.
